IMPROVEMNT IN SArVllN'G--MACHINE.`

The Schedule referred to in these Letters Patent and making paxt. of thesame To all 'who-m `Muay concern:

Be it known that I, ARCHIBALD Innnv, of Richland, in thecounty of Rush,and in the State of Indi ana, have invented `certain new and usefulImprovements in sawing-Machines; and do hereby-r declare that thefollowing is a full, clear, and exact description `tl1ereof,referenceheilig had to the accompanying drawings, and to thevletters of referencemarked thereon.

The object of my invention is to provide a saw-mill that shall b'e`light land portable `in its construction, `the mechanism of which shallbe s'o arranged as "to give greater strength to themovemcnts of thesaw,and yet require a less amount of steam to run it.

` Figure 1 represents a side elevation of my machine.

Figure 2 is a section of the same.

Figure 3 is an end view of the saw, showing the manner in which it isattached to `the frame.

Letter A represents the frame of my machine, which is provided, upon itstop, with a track, B, upon'which the carriage O', which brings thelumber up against the Saw, is moved.

Attached to the driving-shaft is the wheel D, pivoted to which is arm E.

One end of this arm is attached to one side of the wheel D, while theother is secured to the rocking lever F, 'so that when the'wheel is onceset in motion,

4the arm communicates it lto the lever.

rlhis lever is balanced or hung upon the shaft G, and is of a triangularor harp-shape, as seen'in iig. 2, having one of its corners attached tothe lower end of the saw H, by means of aplate or clamp, so that whenthe lever is made `to rock, it imparts a reciprocating motion to theblade. g

Both ends of this saw are provided with clasps I,

attached to the same side of the blade, which Vmove up and down inslides, as seen in iig. 3. 'By having these clasp'sand slides on thesame side of -the saw, the blade cannot he made to vibrate', andis'nnic-li more regular and even in its stroke.'

` Letter J represents an upright beam, `one of which is on each side ofthe frame, and which have a crossheam, extending from their tops, acrossfrom one side to the other.. i i

Extending outward `from this cross-beam is the head-block, to which theupper end of the saw'is attached. v

Upon the outer end ot' the shaft G, upon which the rocking lever ishung, there placed a small crank,

K, for the purpose of operating the lever L, which operates `thefeed-mechanism.

This lever is pivoted to the side of the upright beam J, and has itsupper end slotted to a considerable distance down, so that the arm M,which is secured to it,

. can bemoved nearer to or further from thc centre of motion, wherebythe `length 4of its stroke is made longer or shorter, as the case mayneed. 4

Letter M is the arm, one end of which is attachedto thelever L, asalready described, while the other one is furnished with a clamp, N,sufficiently wide and large to clasp the. top of the iwheel O, and bymeans of which the said wheel is opmated, so as to move the 'carriage (ltoward the saw.

In order to make the clamp N grasp the wheel, and hold it in its place,the spring l has been provided, one cnd of which is attached to the beamJ.

Upon thel same shaft as the wheel D, there` is a second wheel or pulley,as seen in dotted lines in tig. 2, over which a belt, 1t, is passed, soas to communi cate motion to the wheel S.

1 is a friction-wheel, attaclu-rdto the same shaft asv the wheel S, andis-used to reverse the mot-ion ofthe wheel O, so-as to move the carriageback from the saw. The outer part of the -franie upon which this wheel'l has its bearings, is only pivoted on to the main part, so that it canbe moved up and down, in order to be brought in contact with theperiphery oi' the wheel O.

One end of this movable bearing U is attached to the rod Y, which passesup to the top of the frame, where it is secured to the lever W, by whichthis wheel T is brought into contact with the one O.

The carriage Gis composed (if/two parts, which are' united. or formedtogether by means of the` ybar or beam' X, as seen in lig. 2, the lowerpart of which is provided with a toothedrack, which is operated by vthecog-wheel Y. This cog-wheel is attached to the .same shaft as thel wheelO, and` is operated by it.

'lo the side of, the beam J is secured a roller, la, over which a cordpasses, so that the arm M can he lowered and raised. y

On the inside of the beam J is placed the spring u, as shown in dottedllines in iig. l1, the lower end of which is secured to .the clamp N bymeans of the cord c, so that after the arm M has moved the clamp to itsfull length,- the spring (l. draws it back so as to take a new hold'.

livoted to the cross-beam extending across the top of theframe, is thelever (I, to the end of which are atv tached two cords, e and j'.

In order to prevent the wheel from turning backward,`after it has beenpropelled forward by the arm- M, the brake g has been provided, which ishinged to the beam J, and is attached to the cord j',

The mode of operating my machine is as follows:

The motive-power is applied to the shaft 'upon which the wheel 1) isplaced, and the motion being communicated tothe rocking lever l", thesaw is'vset. in motion. `The crank li, revolving, causes the lever L tooscillatc, aml this communicating motion to thc arm M, theivhccl O isslowly propelled around, and this' causing the cog-wheel Y to revolve,which works in the toothed rack of theI carriage, the object to be sawedisthus brought up to the saw.

As soon as the sawing-operation is completed, and

. wheel T so as to come in contact with the wheel O,

when the motion is at. once reversed, and the carriage moved back.

Having thus described my invention, R

That- I claim, and desire to secure b v Letters Iatent is- ,v

1. The lever L, slotted or open at each end, in combina-tion with thecrank K, arm M, and clamp N, when used in the manner and for the purposeas specified.

2. The forked lever L, crank K, arm M, and clamp N, in combination withthe rockingr lever F, shaft G,

'crank K, pitman E, and wheel D, all constructed and opemt-ingsubstantially as set forth. f--3. Thearm M, so arranged and constructedas to be moved nearer -to and further from the centre of and for thepurpose as set forth.

5. The saw H, connected at the top and bottom t0 the slides I I on thesame side, and operated by the rock-ing lever Il, all substantially asset forth.

(5. rIheeombimition of the lever L, arm M, clamp N, springs (L and I),cords c, e, and f, lever al, and bra-ke g, all construct-ed and arrangedto operate substantially in the manner and for the purposes herein setforth.

' In testimony that I claim the foregoing, I have hereunto set my hand,this 5th day of' March, 1869.

ARCHIBALD PERRY. Witnesses:
